90X Speaker question - patrician56 - 01-08-2018

    Hi, Yet another newbie here.

I received a very clean 90X ( 2 type 47 push pull output tubes model) from the family that purchased it new in Bridgeport, CT in 1932. 
I am in the "getting to know you" phase  with this radio and noticed that the field coil on the speaker seem to be loose. I can move the coil 1/8" front to back and it will slightly twist around the armature. 
This aroused my "I know enough to make me dangerous" gene which brought me to the forum to ask if the field coil was cemented or perhaps wedged in place? I don't think that loose is correct.
Any thoughts? 

Thanks in advance, 
Fran

I don't think it's a problem.

I've had speakers like that myself that seem to work fine. If it works ok, just leave it alone.

I've noticed that a lot of the older Philco speakers have field coils that appear to be loose.

As Mike and Jayce said, leave it alone, it's likely OK as long as it isn't shorted to the frame.
